Abstract: A gel-forming composition comprising a first substance selected from the group consisting of a polyvinyl alcohol, a polyvinyl alcohol copolymer, and mixtures thereof, aldehyde operable for cross-linking with the first substance, and water. The gel-forming composition is useful for filling voids in porous substances and for retarding the flow of fluids in subterranean formations. For example, a method is provided for retarding the flow of fluids in high permeability channels in an oil reservoir. Such method is particularly useful in waterflood operations to increase the sweep efficiency of the oil recovery process. Since these gels have very good stability at elevated temperature they can be used in reservoirs having an average in situ temperature of 80<o>C or higher.

Title: Method and instrument for mass analyzing samples with a quistor
Inventor: GABLING REEMT-HOLGER
IPC: H01J49/42
Filed: 1990-02-16
Granted: 1998-05-12
Abstract: A method for the measurement of mass spectra by three dimensional quadrupole fields (QUISTORs) is presented, in which the ions are mass-to-charge selectively ejected by the effect of a natural sum resonance in an inharmonic QUISTOR. In order to enhance scan speed and mass resolution, the ejection of a single kind of ions can be confined to a very small time interval, either by the generation of ions within a small volume outside the field center, or by an excitation of the secular amplitudes by an additional RF voltage across the end electrodes, shortly before the ions encounter the sum resonance condition in the course of the scan. An instrument for this method is described.

Title: Snow making, multiple nozzle assembly
Inventor: RINGER THOMAS RAYMAN
IPC: F25C3/04
Filed: 1990-04-27
Granted: 2002-07-09
Abstract: A snow making, multiple nozzle assembly is provided comprising a tubular casing having an upstream end wall and an outwardly bulging downstream wall containing a plurality of snow making, supersonic, air expansion and liquid atomizing nozzle orifices circumferentially spaced therearound with radially inwardly extending air grooves therebetween in the outer, bulging surface. A tube plate partitions the casing interior into an upstream water compartment and downstream air compartment, and for each snow making nozzle orifice contains a water jet nozzle for directing a water jet into a central portion of that snow making nozzle orifice. Pressurized water fed into the water compartment causes water jets in each of the snow making nozzle orifices while pressurized air fed to the air compartment causes a jacket of air to surround the water jets entering the snow making nozzle orifice. The water exits from the snow malting nozzle orifices as fine droplets which form into snow. One of the snow making nozzle orifices may be replaced by a snow nucleating nozzle orifice.

Title: Modulator and demodulator for data transmission systems
Inventor: YOSHIDA ATSUSHI
IPC: H04L27/38
Filed: 1990-07-27
Granted: 1995-01-03
Abstract: A MODEM has a delay equalizer for receiving a trellis-coded test signal transmitted from an opposite MODEM and compensating for delay distortion of this test signal on the transmission path.  The output of this delay equalizer and the input test signal are selectively entered into a demodulator.  The output of this demodulator is assigned to predetermined signal point coordinates by a decision circuit.  A Viterbi decoder computes a branch metric representing the distance between each assigned point and receive signal point from the output signals of the decision circuit and the demodulator, and figures out the pass metrics of accumulated values based on the branch metrics so computed.  A difference signal represents the difference between the maximum and minimum values of the pass metrics from the Viterbi decoder.  A first difference signal corresponds to the pass metrics when the delay equalizer is not set for the transmission path, and a second difference signal corresponds to the pass metrics when the delay equalizer is set for the transmission path.  A control circuit compares the first and second difference signals and sets the delay equalizer out of the transmission path if the first difference signal is greater than the second, or sets the delay equalizer in the transmission path if the second difference signal is greater than the first.  Thus the MODEM automatically decides whether the delay equalizer is to be inserted in the transmission path.
